While numerous methods and algorithms for HPO have been proposed over the last years, little progress has been made in illuminating and examining the actual structure of these black-box optimization problems. Exploratory landscape analysis (ELA) subsumes a set of techniques that can be used to gain knowledge about properties of unknown optimization problems. In this paper, we evaluate the performance of five different black-box optimizers on 30 HPO problems, which consist of two-, three- and five-dimensional continuous search spaces of the XGBoost learner trained on 10 different data sets. This is contrasted with the performance of the same optimizers evaluated on 360 problem instances from the black-box optimization benchmark (BBOB). We then compute ELA features on the HPO and BBOB problems and examine similarities and differences. A cluster analysis of the HPO and BBOB problems in ELA feature space allows us to identify how the HPO problems compare to the BBOB problems on a structural meta-level. We identify a subset of BBOB problems that are close to the HPO problems in ELA feature space and show that optimizer performance is comparably similar on these two sets of benchmark problems. We highlight open challenges of ELA for HPO and discuss potential directions of future research and applications.","lang":"eng"}],"status":"public","publication":"Parallel Problem Solving from Nature — PPSN XVII","type":"conference","language":[{"iso":"eng"}],"_id":"46306","department":[{"_id":"34"},{"_id":"819"}],"user_id":"15504","place":"Cham","year":"2022","page":"575–589","citation":{"chicago":"Schneider, Lennart, Lennart Schäpermeier, Raphael Patrick Prager, Bernd Bischl, Heike Trautmann, and Pascal Kerschke. “HPO x ELA: Investigating Hyperparameter Optimization Landscapes by Means of Exploratory Landscape Analysis.” In <i>Parallel Problem Solving from Nature — PPSN XVII</i>, edited by Günter Rudolph, Anna V.

This work sheds light on the effects that multi-objective optimization may have in the single-objective space. For this purpose, we examine the inner mechanisms of the recently developed sophisticated local search procedure SOMOGSA. This method solves multimodal single-objective continuous optimization problems based on first expanding the problem with an additional objective (e.g., a sphere function) to the bi-objective domain and subsequently exploiting local structures of the resulting landscapes. Our study particularly focuses on the sensitivity of this multiobjectivization approach w.r.t. (1) the parametrization of the artificial second objective, as well as (2) the position of the initial starting points in the search space. As SOMOGSA is a modular framework for encapsulating local search, we integrate Nelder–Mead local search as optimizer in the respective module and compare the performance of the resulting hybrid local search to its original single-objective counterpart. We show that the SOMOGSA framework can significantly boost local search by multiobjectivization. Hence, combined with more sophisticated local search and metaheuristics, this may help solve highly multimodal optimization problems in the future."}],"status":"public","publication":"Natural Computing","type":"journal_article","language":[{"iso":"eng"}],"_id":"46308","department":[{"_id":"34"},{"_id":"819"}],"user_id":"15504","year":"2022","intvolume":"         1","page":"1–15","citation":{"apa":"Aspar, P., Steinhoff, V., Schäpermeier, L., Kerschke, P., Trautmann, H., &#38; Grimme, C.

However, sensitive personal information, such as documents with people{’}s profiles or relationships as edges, are prone to privacy leaks, as the trained model might reveal the original input. Although differential privacy (DP) offers a well-founded privacy-preserving framework, GCNs pose theoretical and practical challenges due to their training specifics. We address these challenges by adapting differentially-private gradient-based training to GCNs and conduct experiments using two optimizers on five NLP datasets in two languages. We propose a simple yet efficient method based on random graph splits that not only improves the baseline privacy bounds by a factor of 2.7 while retaining competitive F1 scores, but also provides strong privacy guarantees of epsilon = 1.0. We show that, under certain modeling choices, privacy-preserving GCNs perform up to 90{%} of their non-private variants, while formally guaranteeing strong privacy measures."}],"status":"public","_id":"48299","user_id":"15504","department":[{"_id":"34"},{"_id":"820"}],"language":[{"iso":"eng"}]},{"place":"Gyeongju, Republic of Korea","year":"2022","citation":{"chicago":"Igamberdiev, Timour, Thomas Arnold, and Ivan Habernal. “DP-Rewrite: Towards Reproducibility and Transparency in Differentially Private Text Rewriting.” In <i>Proceedings of the 29th International Conference on Computational Linguistics</i>, 2927–2933.

In practice, existing systems may lack the means to validate their privacy-preserving claims, leading to problems of transparency and reproducibility. We introduce DP-Rewrite, an open-source framework for differentially private text rewriting which aims to solve these problems by being modular, extensible, and highly customizable. Our system incorporates a variety of downstream datasets, models, pre-training procedures, and evaluation metrics to provide a flexible way to lead and validate private text rewriting research. To demonstrate our software in practice, we provide a set of experiments as a case study on the ADePT DP text rewriting system, detecting a privacy leak in its pre-training approach. Our system is publicly available, and we hope that it will help the community to make DP text rewriting research more accessible and transparent.","lang":"eng"}],"status":"public","_id":"48300","user_id":"15504","department":[{"_id":"34"},{"_id":"820"}],"language":[{"iso":"eng"}]},{"doi":"10.18653/v1/2022.acl-short.87","title":"How reparametrization trick broke differentially-private text representation learning","author":[{"full_name":"Habernal, Ivan","id":"101881","last_name":"Habernal","first_name":"Ivan"}],"date_created":"2023-10-19T08:26:35Z","publisher":"Association for Computational Linguistics","date_updated":"2023-10-19T12:05:39Z","citation":{"apa":"Habernal, I.
